Bricks are boomer tech now. India recently celebrated the opening of its first-ever 3D printed post office. Located in Bengaluru—the capital and largest city of the southern Indian state of Karnataka—the bold structure was made possible through a collaboration between the Indian Institute of Technology (IIT) Madras and multinational engineering conglomerate Larsen & Toubro.

The post office was completed in just 43 days—two days ahead of schedule—and is being heralded as a showcase of the efficiency and potential of 3D printing technology.

India’s Minister for Railways, Communications, Electronics & Information Technology, Ashwini Vaishnaw, praised the 1,021-square-foot construction project, saying that such accomplishment reflects the philosophy of a self-reliant India. The concept, attributed to Atmanirbhar Bharat, is frequently cited by the government as representative of its plans to lead the nation towards a more developed, powerful economy.

To build the post office, a robotic 3D printer methodically placed layers of specialized concrete, resulting in a cohesive structure with no vertical joints. This process also makes it possible to build curved structures without the limitations of traditional flat walls, which need structural reinforcements to avoid collapsing.
